Jeremy Wagner, a death metal guitarist turned horror book writer, and his wife Kym Foglia paid $10.9 million for the newly built waterfront home at 6411 Allison Road in Miami Beach, a source told The Real Deal.

In addition to writing horror novels, Wagner founded the Chicago-based death metal band Broken Hope. He and his wife paid nearly $1,300 per square foot for the house.

Spec home developer Todd Michael Glaser sold the eight-bedroom, 8,500-square-foot home. The deal, which includes furnishings, closed on Wednesday, Glaser said. He built the home with the intention of living in it, but decided to sell it when he had the opportunity to buy 6650 Allison Road, which he’s developing for himself.

Glaser and his wife Kim bought the waterfront, 17,300-square-foot lot in 2014 for nearly $3.9 million. Glaser said the deal marks a record for a house on Allison Island, surpassing an $8.7 million sale.

The contemporary home, designed by Domo Architecture + Design, features a guest house toward the entrance of the property, a gourmet kitchen, media room, two-car garage, heated pool and spa, koi pond and outdoor shower. David Hunt Solomon of EWM Realty International was the listing agent, and Julian Johnston of Calibre International Realty brought the buyer, Solomon and Johnston confirmed. Attorney Mark Meland also worked on the deal.

It was last listed for $12.49 million. Lowering the price from the original $13.9 million ask helped bring in offers, Solomon said.

Johnston declined to name the buyers but said they were looking for a clean, modern and bright house to spend about nine months out of the year. The luxury home market in Miami Beach has improved over the past five or six months because prices have come down about 10 to 15 percent, he added.

“What’s going to happen is Allison Island is going to be the next place to pop,” Solomon said, citing the larger lot sizes and value on a price-per-square-foot basis.

In 2014, Michael Burke, CEO of luxury fashion brand Louis Vuitton, paid $11.7 million for a teardown on Allison, marking the most expensive land deal on the island.
